## Facts

- Tool: `show`
- Server: Lint (`Dave-London/Pare`) — https://policylayer.com/tools/io-github-dave-london-lint.md
- Homepage: https://github.com/Dave-London/pare
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "show",
    "arguments": {}
  }
}
```

## Why show is rated Low

This tool performs a read-only query of version control metadata (commit details, diff statistics). It has no side effects and does not create, modify, execute, or delete anything. The blast radius of misuse is minimal—an agent could learn commit history or diff information, but cannot cause harm. Confidence is high because the description clearly indicates read-only retrieval operations.

From the tool's own definition: "Tool 'shows commit details and diff statistics for a given ref' — retrieves and displays information about commits and diffs without modifying or executing anything."

## Use case

AI agents call show to retrieve information from Lint without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Lint:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "show": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
